Just to point out... the vita 2000 was released in Q2 (calendar) 2014. It was bundled with Borderlands 2.
Theres also the PS TV which usually gets agregated into vita sales.
And in terms of support.... the Vita gets weekly releases, and 2 free games a month from your PS+ sub, and most importantly is 1,000,000x better than the gamepad for remote play.
